i wonder if someone used the number of guns sold in each caliber to come up with these facts.the 30-30 has been aroundfor over a hundred years now and it has always been very reasonable to buy. years ago people did not spend more than it took to do the job.being no reason to buy anything bigger or more expensivethat a 30-30 for deer hunting. i just wonder if the 30-30 has the record for sales in the centerfire.
